Desempenho de plantas de cobertura estivais e influência em atributos de solo em unidade didática no Sudoeste do Paraná

Abstract: O cultivo de plantas de cobertura no sul do Brasil é predominante no período de inverno, apesar de existir espécies adaptadas para o período de verão, são limitadas as informações sobre o comportamento destas para a região. Deste modo, objetivou-se avaliar o desenvolvimento de fabáceas estivais, em diferentes épocas de semeadura e seus efeitos no teor de N e densidade do solo (Ds). O experimento foi implantado em 2010, com 10 espécies de plantas de cobertura, semeadas em cinco épocas, de novembro a março de ca… Show more

“…Oliveira et al (2021a) mentioned that for sowing carried out from early October to early November, nitrogen accumulation in the shoot biomass of crotalaria juncea oscillated around 300 kg ha -1 , confirming the observations of Perin et al (2004) andDuarte Júnior andCoelho (2008). Of the total nitrogen accumulated in the shoot biomass of crotalaria, about 60% to 70% originated from the symbiotic associations of legume roots with the atmospheric N2fixing bacteria, resulting in the contribution of significant amounts of this nutrient to the soil-plant system (Perin et al, 2004), thus contributing to greater sustainability of the subsequent crop (Mascarenhas et al, 1994;Lima et al, 2010 andHaskel et al, 2020). For comparative purposes, ammonium sulfate, one of the most used nitrogen fertilizers is cited.…”

“…As previously mentioned, the growth rate and dry matter accumulation in the shoots of the cover plants are influenced by several factors, especially water and nutrient availability in the soil, temperature, luminosity, plant yield potential and evaluation period (Ernani et al, 2001;Meda, 2003;Haskel et al, 2020;Oliveira et al, 2021a). In this study, brachiaria brizantha surpassed brachiaria ruziziensis in dry matter accumulation, but there are reports in the literature of comparable dry matter accumulation by ruziziensis.…”
